Figure 3: An illustration of the result of the noise detection process on pixels' intensities. The left figure is an example of the pixels' intensities in a 5×5 neighborhood while the figure on the right shows the result of the detection process. In the right image, a higher value means the pixel considered to be noise. (a) A noise-likely pixel and (b) Edge-likely pixels
